    Abstract: In exemplary embodiments, methods and systems are provided for controlling emissions for a drive system for a vehicle. In one embodiment, the system includes: one or more first sensors configured to measure an engine temperature pertaining to an engine of the vehicle; one or more second sensors configured to measure an ambient temperature surrounding the vehicle; one or more third sensors configured to detect an amount of running time in which the engine has been running; and a processor coupled to the one or more first sensors, the one or more second sensors, and the one or more third sensors and configured to at least facilitate controlling emissions for the drive system based on the engine temperature, the ambient temperature, and the amount of running time in which the engine has been running.

    Abstract: An engine control system for a vehicle includes a timer module, a stochastic pre-ignition (SPI) mitigation module, and a boost control module. The timer module tracks a period of operation of an engine where vacuum within an intake manifold is less than a first predetermined vacuum. The SPI mitigation module generates an SPI signal when the period is greater than a predetermined period and the vacuum is less than a second predetermined vacuum. The second predetermined vacuum is less than the first predetermined vacuum. The boost control module reduces output of a turbocharger in response to the generation of the SPI signal.

    Abstract: A fuel system comprises a first fuel rail. A first fuel delivery system, including a first plurality of fuel injectors, is connected to the first fuel rail. The first plurality of fuel injectors injects an amount of fuel into a first portion of an engine. A second fuel rail has a second fuel delivery system, including a second plurality of fuel injectors. The second plurality of fuel injectors inject an amount of fuel into a second portion of the engine, distinct from the first portion. A controller, operatively connected to the first fuel delivery system and the second fuel delivery system selectively enables and disables operation of the first fuel delivery system and the second fuel delivery system based on one of a detected temperature and a detected pressure of fuel passing to corresponding ones of the first plurality of fuel injectors and the second plurality of fuel injectors.
